Abstract

Research studies were conducted to screen 110 cowpea genotypes against Callosobruchus maculatus commonly known as the cowpea weevil, under the no-choice infestation condition. Out of all the genotypes screened, BBBT1-11 outperformed all the genotypes across all parameters investigated. BBBT1-11 recorded 13.01 no. of eggs/100 seeds compared to MS1-8-2-6-9-1 with 128.67 eggs/100 seeds. The adult emergence on BBBT1-11 was at 12.72% compared to the highest LTBT1-5 at 88.11%. The lowest growth index of 0.42 and frass of 0.23g was recorded on BBBT1-11. BBBT1-11 could be further assessed for the possible presence of biochemical substances, which could explain the observed differences among the genotypes in their reaction to C. maculatus. Besides, BBBT1-11 can also be incorporated into the breeding program with the target of breeding cowpea varieties that are tolerant to pest infestation.
